Acroname 614906 Polaroid Ranging Module used in SX-70 camera TI SN28827 Sonar Ranging Module (1983, maybe even earlier...)

technology that Polaroid Cameras use - measure
the time it takes to send out an ultrasonic pulse and wait
for that sound wave to bounce off an object and return to
the source. The Distance Probe has an accuracy of ± 7 mm
over its entire temperature range (0 ºC to 52 ºC). The
Probe range is 0.4 m to 10 m. Distance Probe (De)struction
Snapped off one of the flat plate
mounting flippers? from my distance probe. Upon further
investigation, there are four latches in the square body
that the tips were hot glued into place... Looks like
early versions had four working latches which failed over
time. This left the Distance Probe unable to fasten to a
vertical plate, or whatever it was to attach to.
